Abstract: The software applies the BIM technology in the aluminum formwork design process, which employs the independently developed 3D modeling technology for digital structures, to achieve the seamless docking and data connection between the data of engineering entity of building and data of aluminum template design. The software is able to conduct the visible construction simulation of the aluminum template based on the 3D digital building model, as well as the collision and leakage check of the template, to improve the accuracy and efficiency of the design.
